RADIATION HAZARDS IN SPACE FLIGHT [PDF]

open access: green, 1958
The knowledge pertinent to dose evaluation is reviewed for conditions of flight in space in the vicinity of the earth but away from the influence of its atmosphere or magnetic field. Certain properties of the heavy nuclei are also discussed as well as some of the available information on their actual biological effects.

Stress Related Shift Toward Inflammaging in Cosmonauts After Long-Duration Space Flight

open access: yesFrontiers in Physiology, 2019
Space flight exerts a specific conglomerate of stressors on humans that can modulate the immune system. The mechanism remains to be elucidated and the consequences for cosmonauts in the long term are unclear. Most of the current research stems from short-

Osteocyte biology and space flight [PDF]

open access: yesCurrent Biotechnology, 2013
The last decade has seen an impressive expansion of our understanding of the role of osteocytes in skeletal homeostasis. These amazing cells, deeply embedded into the mineralized matrix, are the key regulators of bone homeostasis and skeletal mechano sensation and transduction. They are the cells that can sense the mechanical forces applied to the bone

Magnesium and Space Flight [PDF]

open access: yesNutrients, 2015
Magnesium is an essential nutrient for muscle, cardiovascular, and bone health on Earth, and during space flight. We sought to evaluate magnesium status in 43 astronauts (34 male, 9 female; 47 ± 5 years old, mean ± SD) before, during, and after 4–6-month space missions.

NASA Satellite Measurements Show Global‐Scale Reductions in Free Tropospheric Ozone in 2020 and Again in 2021 During COVID‐19

open access: yesGeophysical Research Letters, 2022
NASA satellite measurements show that ozone reductions throughout the Northern Hemisphere (NH) free troposphere reported for spring‐summer 2020 during the COronaVIrus Disease 2019 pandemic have occurred again in spring‐summer 2021.
